Abstract
Description
Technical Field
[0001] This invention relates to the field of grounding pile technology, specifically to an adaptive temporary grounding pile structure. Background Technology
[0002] In power construction and equipment maintenance, temporary grounding piles are crucial for ensuring operational safety. Their function is to quickly conduct leakage current or lightning strike current into the ground, preventing electric shock to personnel or damage to equipment. However, existing temporary grounding piles have the following prominent problems in practical applications: 1. Low installation efficiency: In hardened road surfaces (such as concrete and asphalt) or hard soil environments, manual hammering or mechanical forced driving is required, which is not only time-consuming, but also easily leads to bending and deformation of the pile body. 2. Significant safety hazards: Insufficient burial depth or excessive grounding resistance occurs frequently, which may lead to leakage accidents; 3. Cumbersome operation: The burial depth needs to be measured manually, the process is complicated, and human error is easy to occur.
[0003] Therefore, in order to improve the effectiveness of grounding piles and to promote technological advancement and enhance core technological competitiveness in the industry, this application proposes a new implementation scheme that differs from the structure and application of temporary grounding piles in existing technologies. Summary of the Invention (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an adaptive temporary grounding pile structure, primarily to solve the problems of low installation efficiency, significant safety hazards, and cumbersome operation during the installation of temporary grounding piles.
[0004] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: An adaptive temporary grounding stake structure includes a grounding stake assembly, which comprises a stake body, a drill bit for powerful ground breaking, and a connector that matches the impact drill. The bottom of the stake body has a first protrusion integrally formed, the top of the drill bit has a first groove that engages with the first protrusion, the top of the stake body has a second groove, the outer surface of the stake body has a locking hole through which a grounding plate is inserted, the outer surface of the stake body is threaded with a fastening screw that passes through the grounding plate, the bottom of the connector has a second protrusion integrally formed and engages with the second groove, and the top of the connector has a square shank integrally formed.
[0005] Furthermore, the pile body is made of Q235 carbon steel round bar, and the drill bit is made of tungsten steel YG8 cutter head and 40Cr cutter body.
[0006] Based on the aforementioned scheme, chip removal grooves are provided on the surfaces of the pile body and the drill bit.
[0007] As a further embodiment of the present invention, the outer surface of the pile body is provided with a marking line.
[0008] Furthermore, the top of the drill bit is fitted with a angular chisel, which is a 135° alloy hammer drill bit.
[0009] Based on the aforementioned scheme, the first boss and the second boss are trapezoidal structures.
[0010] As a further embodiment of the present invention, the outer surface of the grounding plate is provided with a plurality of mating holes.
[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides an adaptive temporary grounding stake structure, which has the following beneficial effects: 1. This invention, through the "drilling and piling integration" design, combines a hardened alloy cutter head with a highly conductive pile body, and with a visual burial depth marker and an electric impact drill adapter interface, achieves a one-step process from ground breaking to pile burial, greatly simplifying the operation process, reducing manual labor intensity, and avoiding human error through clear burial depth markings, eliminating safety hazards caused by insufficient burial depth or excessive grounding resistance, and reducing the risk of electric shock.
[0012] 2. Compared with the traditional method of manually hammering or mechanically driving in 3 grounding piles, the single-group operation of this invention (3 grounding piles) reduces the time from 60 minutes to 15 minutes, significantly improving efficiency and reducing the risk of pile bending and deformation.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0016] Reference Figures 1-6 An adaptive temporary grounding pile structure includes a grounding pile assembly, which consists of a pile body 1, a drill bit 5 for powerful ground breaking, and a connector 13 that matches the impact drill. Chip removal grooves 2 are formed on the surfaces of the pile body 1 and the drill bit 5. The chip removal grooves 2 have a U-shaped structure to promptly remove debris and improve the smoothness of pile driving. A first boss 3 is integrally formed at the bottom of the pile body 1. A first groove 4 is formed at the top of the drill bit 5, and the first groove 4 engages with the first boss 3. A second groove 6 is formed at the top of the pile body 1. A locking hole 9 is formed on the outer surface of the pile body 1, and a grounding plate 10 is inserted through the locking hole 9. A fastening screw 11 is threaded onto the outer surface of the pile body 1, and the fastening screw 11 passes through the grounding plate 10. A second boss 14 is integrally formed at the bottom end of the connector 13, and the second boss 14 engages with the second groove 6. A square shank 15 that can be matched with an electric impact drill is integrally formed at the top of the connector 13.
[0017] Among them, pile body 1 is made of Q235 carbon steel round bar with galvanized surface treatment to further increase its conductivity, and drill bit 5 is made of tungsten steel YG8 cutter head and 40Cr cutter body.
[0018] The outer surface of the pile body 1 is marked with a marking line 8. Starting from the drill bit 5, every 100mm above 600mm, the marking line 8 is laser-engraved on the surface of the pile body 1. This can intuitively reflect the current burial depth of the grounding pile. The top of the drill bit 5 is fitted with an angle chisel 7, which is a 135° alloy electric hammer drill bit. The first boss 3 and the second boss 14 are trapezoidal structures. The outer surface of the grounding plate 10 is provided with multiple docking holes 12 for connecting to the ground wire.
[0019] The working principle of this embodiment is as follows: When in use, firstly, the first groove 4 on the drill bit 5 is engaged with the first protrusion 3 at one end of the pile body 1. Then, the second protrusion 14 on the connector 13 is engaged with the second groove 6 at one end of the pile body 1. The output end of the impact drill is engaged with the square handle 15, thereby driving the connector 13, the pile body 1 and the drill bit 5 to rotate. For soft soil, hard clay and concrete hardened ground, the drill bit 5 is used as an impact drill bit to forcefully break the ground. After reaching the preset pre-buried depth, i.e. 600mm red warning line, the docking hole 12 on the grounding plate 10 is fixed to the grounding wire. Then it can be used directly as a temporary grounding pile.
